A device has four legs each leg having a plurality of teeth. The device further includes a body which has four gears wherein each of the four gears meshes with the teeth of a different leg. A first gear is connected to a second gear by a first shaft, and a third gear is connected to a fourth gear by a second shaft. The first gear meshes with the third gear, and the second gear meshes with the fourth gear. The legs can be selectively positioned to a retracted position adjacent to the body or to an extended position projecting away from the body. A biasing mechanism urges the four legs to the extended position. A locking mechanism locks the legs in either the retracted position or the extended position.
